Abstract
In this paper, the me tabolic regulation mechanism of microorganisms in food and the strategies and applications of product optimization were discussed. Firstly, the complex mechanisms of microbial me tabolism regulation were analyzed, including dynamic regulation of enzyme activity, fine control of enzyme synthesis, balance regulation of energy charge and multi-level cooperative regulation, which together ensure the survival and reproduction of microorganisms under different environmental conditions. Subsequently, this paper elaborated on the effective optimization of microbial me tabolites through nutrient regulation, environmental condition optimization, genetic engineering transformation and me tabolic engineering strategies, aiming at improving the yield, purity and biological activity of target products. In the field of food industry, the application of microbial me tabolism regulation has shown great potential and value. The efficiency and product quality of food fermentation were significantly improved by screening and improving efficient microbial strains, optimizing fermentation medium composition and ratio, and precisely regulating fermentation process parameters. At the same time, the use of microbial me tabolism regulation technology, successfully developed a series of new food additives, such as natural pigments, biological preservatives and functional ingredients, these additives not only improve the nutritional value of food and sensory quality, but also enhance the safety and stability of food. In addition, microbial me tabolism regulation also plays an important role in reducing the production of harmful substances in food, controlling food safety risks and removing pollutants in the fermentation process. In summary, microbial me tabolism regulation and product optimization technologies provide strong support for the innovation and development of the food industry, and are of great significance for promoting the green, healthy and sustainable development of the food industry.
